This is what befalls your body when you are obstructed.

When you are constipated, your bowel movements become infrequent, and stool becomes hard and difficult to pass. This is often due to the colon absorbing too much water from the stool, or because the colon's contractions are not strong enough to push the stool out. Symptoms can include abdominal discomfort, bloating, and straining during bowel movements. Chronic constipation can lead to further complications such as hemorrhoids or anal fissures.
